4. Setup and Installation
Installing the MONTERAL Activated Carbon Refrigerator Filter is a quick and straightforward process. Follow these steps to ensure proper placement and function:
- Locate the Filter Compartment: Most compatible refrigerators have a dedicated filter compartment, often located at the back of the refrigerator interior or near the fan assembly. Consult your appliance's manual if you are unsure.
- Remove the Old Filter (if applicable): Gently twist or unclip the old filter from its housing. Dispose of the old filter responsibly.
- Insert the New Filter: Align the new MONTERAL filter with the compartment. It should fit snugly.
- Secure the Filter: Twist or clip the new filter into place until it is securely seated. Ensure it does not wobble.
The filter can be positioned at the back of the refrigerator for optimal air circulation and odor absorption.

5. Operating Principle
The MONTERAL Activated Carbon Refrigerator Filter works by utilizing the highly porous structure of activated carbon. As air circulates within your refrigerator, it passes through the filter. The activated carbon then adsorbs (attracts and holds) odor molecules and other airborne impurities onto its vast surface area. This process effectively neutralizes unpleasant smells, such as those from strong cheeses, onions, or leftover food, ensuring that your refrigerator maintains a consistently fresh and clean scent. This helps to preserve the natural taste and quality of your stored food items.

6. Maintenance
To ensure the continuous effectiveness of your MONTERAL Activated Carbon Refrigerator Filter, regular replacement is crucial. The activated carbon's adsorption capacity diminishes over time as it becomes saturated with absorbed odors and impurities.
Replacement Schedule:
It is generally recommended to replace the refrigerator filter every 6 months. This timeframe ensures optimal performance and consistent odor absorption. Depending on the usage and types of food stored in your refrigerator, you may consider replacing it more frequently if strong odors persist.
Always dispose of used filters according to local waste disposal guidelines.
7. Troubleshooting
While the MONTERAL Activated Carbon Refrigerator Filter is designed for reliable performance, you might encounter minor issues. Here are some common scenarios and their solutions:
Issue: Odors persist in the refrigerator after filter installation.
- Check Installation: Ensure the filter is correctly and securely installed in its designated compartment. A loose filter may not allow proper air circulation.
- Filter Age: If the filter has been in use for more than 6 months, its adsorption capacity may be exhausted. Replace the filter with a new one.
- Source of Odor: Identify and remove any spoiled food items or spills that might be causing persistent odors. Clean the refrigerator interior thoroughly.
- Overpowering Odors: For extremely strong or unusual odors, it may take a few days for the filter to fully neutralize them. Ensure the refrigerator door is not left open for extended periods.
Issue: Filter does not fit.
- Verify Compatibility: Double-check the model numbers and original codes listed in Section 3 (Compatibility) against your refrigerator's specifications.
- Correct Orientation: Ensure you are attempting to install the filter in the correct orientation as shown in the installation guide (Image 4.1).
